The idea is that as solar costs continue to drop and project economics remain buoyed by the ITC, the case is stronger for utilities to claim losses and expenses as a result of increasing solar adoption.
The form that’s taken so far is an overhaul to net metering policies.
Geothermal heat pumps continue to be eligible for a 10% ITC through the end of 2016, and geothermal electric systems are eligible for a 10% ITC through 2022 and future years.
Utility-scale wind projects continue to be eligible to claim the ITC in lieu of the PTC as long as the PTC is in effect.
Historically, net metering rules have given a 1:1 credit for excess generation meaning every excess k Wh generated is a k Wh credited.
